Answer:
Personally I say the yellow truck but...
Explanation:
It's heavily based on the object's mass...
If you know which object has the most mass than I would choose that one, but personally I think the yellow one has the most mass...
Answer:
The relative uncertainty gives the uncertainty as a percentage of the original value. Work this out with: Relative uncertainty = (absolute uncertainty ÷ best estimate) × 100%. So in the example above: Relative uncertainty = (0.2 cm ÷ 3.4 cm) × 100% = 5.9%. The value can therefore be quoted as 3.4 cm ± 5.9%.

Answer:
89.87m/s
Explanation:
Given the velocity function
v(t)=−t²+3t−2
In order to get the displacement function, we will integrate the velocity function as shown:
![\int\limits^5_{-2} {v(t)} \, dt \\d(t)= \int\limits^5_{-2}{(-t^2+3t+2)} \, dt \\\\d(t)=[\frac{-t^3}{3}+\frac{3t^2}{2}+2t ]^5_{-2}\\](https://tex.z-dn.net/?f=%5Cint%5Climits%5E5_%7B-2%7D%20%7Bv%28t%29%7D%20%5C%2C%20dt%20%5C%5Cd%28t%29%3D%20%5Cint%5Climits%5E5_%7B-2%7D%7B%28-t%5E2%2B3t%2B2%29%7D%20%5C%2C%20dt%20%5C%5C%5C%5Cd%28t%29%3D%5B%5Cfrac%7B-t%5E3%7D%7B3%7D%2B%5Cfrac%7B3t%5E2%7D%7B2%7D%2B2t%20%20%5D%5E5_%7B-2%7D%5C%5C)
at t = 5
![d(5)=[\frac{-5^3}{3}+\frac{3(5)^2}{2}+2(5) ]\\d(5)=[\frac{-125}{3}+\frac{75}{2}+10 ]\\d(5)=-41.7+37.5+10\\d(5)=89.2m/s](https://tex.z-dn.net/?f=d%285%29%3D%5B%5Cfrac%7B-5%5E3%7D%7B3%7D%2B%5Cfrac%7B3%285%29%5E2%7D%7B2%7D%2B2%285%29%20%20%5D%5C%5Cd%285%29%3D%5B%5Cfrac%7B-125%7D%7B3%7D%2B%5Cfrac%7B75%7D%7B2%7D%2B10%20%20%5D%5C%5Cd%285%29%3D-41.7%2B37.5%2B10%5C%5Cd%285%29%3D89.2m%2Fs)
at t = -2
![d(-2)=[\frac{-(-2)^3}{3}+\frac{3(-2)^2}{2}+2(-2) ]\\d(-2)=[\frac{-8}{3}+\frac{12}{2}+(-4) ]\\d(-2)=-2.67+6-4\\d(-2)=-0.67m/s](https://tex.z-dn.net/?f=d%28-2%29%3D%5B%5Cfrac%7B-%28-2%29%5E3%7D%7B3%7D%2B%5Cfrac%7B3%28-2%29%5E2%7D%7B2%7D%2B2%28-2%29%20%20%5D%5C%5Cd%28-2%29%3D%5B%5Cfrac%7B-8%7D%7B3%7D%2B%5Cfrac%7B12%7D%7B2%7D%2B%28-4%29%20%20%5D%5C%5Cd%28-2%29%3D-2.67%2B6-4%5C%5Cd%28-2%29%3D-0.67m%2Fs)
Required displacement = d(5) - d(-2)
Required displacement = 89.2 - (-0.67)
Required displacement = 89.2 + 0.67
Required displacement = 89.87m/s
Answer:
What is the interaction between two different species in an ecosystem called?
Interactions between different species in a community are called interspecific interactions—inter- means "between." Different types of interspecific interactions have different effects on the two participants, which may be positive (+), negative (-), or neutral (0).
